Let's divide 507351 by 70
The aim is to understand the frequency of 70 in 507351.

On to step 1:
The number 70 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 70

Let's proceed to step 2:
If we divide 50 by 70, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 70

On to step 3:
If we divide 507 by 70, we get 7 and a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 490 from 507 and we're left with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 70

Let's proceed to step 4:
When dividing 173 by 70, we get 2 with a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 72.0
The remainder is 33 after subtracting 140 from 173.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 70

Going ahead to step 5:
70 can be fit into 335 4 times, resulting in a remainder of 55.
The next digit of our result is 4. 
Result so far: 724.0
The remainder is 55 after subtracting 280 from 335.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 70

Going ahead to step 6:
When dividing 551 by 70, we get 7 with a remainder of 61.
The next digit of our result is 7. 
Result so far: 7247.0
Subtract 490 from 551 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 7:
The number 70 fits into 610 8 times, leaving a remainder of 50.
The next digit of our result is 8. 
Result so far: 7247.8
Subtracting 560 from 610 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7247.87
Subtracting 490 from 500 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 7247.871
If we take 70 away from 100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 7247.8714
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
70 can be fit into 200 2 times, resulting in a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 7247.87142
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 7247.871428
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
400 divided by 70 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7247.8714285
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
When dividing 500 by 70, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7247.87142857
If we take 490 away from 500, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 7247.87142857 with a remainder of 1e-08.
